Trait IKeyExprTreeNodeMut 

pub trait IKeyExprTreeNodeMut<Weight>: IKeyExprTreeNode<Weight> {
    // Required methods
    fn parent_mut(&mut self) -> Option<&mut Self::Parent>;
    fn weight_mut(&mut self) -> Option<&mut Weight>;
    fn take_weight(&mut self) -> Option<Weight>;
    fn insert_weight(&mut self, weight: Weight) -> Option<Weight>;
    fn children_mut(&mut self) -> &mut Self::Children;
}

The mutating methods of a KeTree node.

Required Methods

fn parent_mut(&mut self) -> Option<&mut Self::Parent>

Mutably access the parent node if it exists (the node isn’t the first chunk of a key-expression).

fn weight_mut(&mut self) -> Option<&mut Weight>

Mutably access the node’s weight.

fn take_weight(&mut self) -> Option<Weight>

Remove the node’s weight.

fn insert_weight(&mut self, weight: Weight) -> Option<Weight>

Assign a weight to the node, returning the previous weight if the node had one.

fn children_mut(&mut self) -> &mut Self::Children

Mutably access the node’s children.
